“Nutrition. That’s the Cheerios Tradition” (1971), and “Oats, the Grain Highest in Protein” (1971). The image on the right is from a 1973 box of Cheerios.
The next mystery 'thingie' was this fish-shaped thing that was in this 10 cent bag of sewing stuff. After 'googling' for what was imprinted on the side (Whale Art Co St Louis Mo), I discovered this is a carpet tool. Who knew?
This was the best find in another bag of sewing stuff for 25 cents. It's the instructions for using the Singer needle threader, dated 1936 and 1937.
Hope you enjoyed a trip through yesteryear!
